\ CLOTHES-WBINGER.

T 0 all whom it may concem:

Be it known that I, ALBERT H. Nn-LLER, a citizen of the United States, residing at Fairfield, in the county of Jefferson and State of Iowa, have invented a new and useful Improvement in Clothes-\Vringers, of which the following is a specification.

My invention relates to that class of wringers or mandrels, wherein a breakable pressure bar is used, or in other words, a pressure bar composed of two parts which are held together to produce pressure on the rolls, and which. may be separated to release the pressure; and it consists of improved connecting means which is simpler, and more reliable, is more easily operated, and will more quickly and surely effect the release of the pressure on the rolls than devices heretofore used for this purpose, and in other features, all of which will be herein explained and more specifically set forth in the claims.

In the accompanying drawings which form a part of this specification, Figure 1 is a perspective of a power operated clothes wringer eml'iodying my invention and showing the pressure bar in released position. Fig. 2 is an elevated section of the upper portion of the wringer showing the pressure bar in operative position. Fig. 3 is a modified detail. 1

Referring to the drawings, A represents the vertical frame work in which the rolls.

B are mounted, and which are held together by horizontal connecting cleats C. The, wringer is also provided with a drain hoard D, all in the usual manner. In Fig. 1 a casing E is shown which surrounds the gearing of an operating mechanism which is driven by a shaft S. F is a lever held in place by a bracket (l for throwing the wringer into and out of gear, and also reversing the movement of the rolls. all in the manner known to the art and for which I make no claim.

H represents the pressure made in two parts or halves. or of a single part cut in two approximately in the center, each of which halves is hinged to the frame Specification of Letters Patent.

of the wringer by pivots I. This may be done in different Ways but the preferable way is to attach an inverted U-shaped clip J to the outer ends of the pressure bar halves, said clips having holes in their lower ends to receive pivot pins connected to plates J secured to the outer edges of the frame of the wringer.

Thumb screws K are inserted in the ends of the pressure bar halves and when in operative position they are adapted to contact near its ends with a metallic bar L which rests on the upper ends of compression springs M, the lower ends of which springs in turn rest upon the bearings of the rolls 13, said bearings being covered by the casings N. The ends of the parts H being extended beyond the outer edges of the \vringer frame, and being hinged at these outside points, will result in a more extended release than if they were hinged within the wringer frame and closer to the thumb screws K in the usual way.

To hold the separated halves of the presmembers 0 and 0', preferably metallic rods bent at right angles near their centers and the outer end of the member 0 being enlarged and made hollow to form a sleeve to receive and rotatably hold the outer end of the member 0. The other ends of the members are connected to the halves of the pressure bar II in a manner to hold them securely in alinement therewith, and be free to rotate laterally while being held in said position.

The preferable plan is to bore lineally extending holes in the meeting ends of the halves of the pressure bar and insert the lower ends of the members 0 and O in said holes. as shown in the drawings. but any other method of attachment which will hold the contacting ends of the members securcl in alinement with the halves of the pressure bar while being free to rotate laterally, will answer the purpose of my invention.

The same is true of the upper ends of the members which are connected together.

. members They must be held substantially parallel with each other while being free to rotate to a certain extent when moved to the side.

The plan shown in Figs. 1 and 2 is preferable but the ends of the members may be joinedtogether in other ways to secure substantial alinement with free rotation of the connected ends within certain limits. A

' modified form is shown by Fig. 3 in which the upper end of the member O is bent over'and perforated to pivotally receive the .upper end of the member 0 and the clip P is secured to the member 0 and pivotally surrounds a portion of themember 0 Fig. 2 shows the halves of the Tpressure bar H in operative position. he connectedends of the members 0 and O are laced in a. substantially vertical position. vhen in this position the halves of the pressure bar will be securely held in a horizontal position and in substantial alinement with each other. The thumb screws being turned down, pressure will be exerted on the ends of the metallic bar and also on the compression springs M whlch in turn will hold the rolls inoperative contact with each other. To release the pressure instantaneously all that is necessary is to tip the connected ends of the members 0 and O'to one side or the other, which will throw them 05 center, when the halves of the pressure bar and the members 0 and 0 will instantaneously assume the released position shown in Fig. 1.

The advantages of this construction over the devices heretofore used for this purpose will be readily apparent. In the first place it operates in either direction by the projecting ends of the members being pushed to one side or the other. lVhen a latch arrangement is used it can only be released in a certain way. The projecting ends of the O and O standing out prominently can be reached and operated by other parts of the body, such as the head or shoulders or elbows as well as the hands. Frequently the important thing is to secure an instantaneous release of the pressure. Something has gone wrong with the clothes or the'operators hands get caught in the rolls, which sometimes occurs.

. The operator may get excited and not beable on the spur of the moment to. do anyting exact. In such cases, all that is necessary to effect an instantaneous release of the pressure on the rolls is to get in some way the projecting ends of the members off center. It makes little difl'erence if the pressure should be excessive the members will always be easily thrown off center and thus release the pressure. In case the operators hand should get caught in the rolls it is ex ceedingly important that an instantaneous release of the pressure be effected, and a sure and readily apparent way to secure this result regardless of excitement is provided by my invention. In addition to this the pressure bar can be easily brought back into operative position by the leverage of the projecting ends of the members w thout having to loosen the thumb screws which cannot be easily done when a latch arrangement is used. There are many advantages in this arrangement which will be obvious to those skilled in'the art.

lVhat I claim is:

1. In clothes wringers, a frame, a pressure bar made in two parts each having its outer end hinged on a horizontal axis adapted to be held in substantial horizontal alinement and to be released therefrom and a pair of retaining and releasing members having their ends set at substantially right angles, the inner ends of said members being rota tably and detachably attached in substantial alinement with the parts of the pressure bar, and the outer ends of said members being held in parallel relation to each other while being free to rotate when said ends are moved to a horizontal position at either side of a vertically central alinement,thereby permitting the free movement upward of {)he inner ends of the parts of the pressure 2. In clothes wringers, a frame, a pressure bar made in two parts each having its outer end hinged on a horizontal axis adapted to be held in substantial horizontal alinement and to be released therefrom, and-a pair of retaining and releasing members having their ends inserted longitudinally in the adjabent ends of the pressure bar parts and being free to rotate therein, and the outer ends of said members being held'in parallel relation to each other while being free to rotate when said ends are moved to a horizontal position at either side of a vertically central alinement, thereby permitting the free movement upward of the inner ends of the parts of the pressure bar.
